摘要
确定节点的位置是无线传感器网络对监测区域相关信息进行感知、采集和处理所面临的首要问题,直接影响它在实际中的应用。文中介绍了无线传感器网络的基本概念、节点位置的计算方法以及典型的移动锚节点路径规划,提出一种基于三边测量法的移动锚节点定位方案。在保证遍历所有未知节点的前提下,该方案的路径规划较为简单,定位精度较高。
Determining the location of nodes is the primary issue for wireless sensor networks in sensing,collecting and processing related information in the monitoring area,which directly affects its application in practice. The basic concept of wireless sensor networks,the calculation method of node location and the typical path planning of mobile anchor nodes are introduced and a mobile anchor node localization scheme based on trilateral measurement is proposed. With all unknown nodes covered,the path planning of this scheme is relatively simple and can reach high accuracy.
